Steve Horvath, Professor of Genetics and Biostatistics at UCLA, studied methylation, a natural process that chemically modifies DNA and how it varies with age. Horvath found that the methylation of 353 DNA markers varied consistently with age and could be used as a biological clock. Horvath showed that the biological clock was reset to zero when cells plucked from an adult were reprogrammed back to a stem-cell-like state. This may be proof of concept that the body clock can be reset.

Nine of the 10 most lucrative degrees in America are in computer science programs at elite colleges. Stanford’s computer science program pays off more than any single major in the country. For the best dollar-for-dollar investment, nothing beats the University of Virginia.

What’s the most valuable college education in the country? Every year PayScale, the largest private tracker of U.S. salaries, tries to answer the question. This year they released their findings in an elegant site that you can play with here.

In an astounding discovery, on Monday the 17th March, Physicists have found a long-predicted twist in light from the big bang that represents the first image of ripples in the universe called gravitational waves, researchers announced today. The finding is direct proof of the theory of inflation, the idea that the universe expanded extremely quickly in the first fraction of a nanosecond after it was born.
